11 Claims. (Cl. 33-56) This invention relates in general to a gunsightassembly and more particularly to a gunsight assembly including apeepsight and means for adjusting the position of the peepsight in twodirections at right angles to each other.

An object of this invention is to provide compact. safe, simple, durableand efiicient means for mounting a gunsight on a gun with provision foradjusting the position of the gunsight in two directions at right anglesto each other, quickly and accurately.

Another object of the invention includes the provision in such anassembly of novel means for securing the adjustable parts of theassembly in selected positions of adjustment. Additional objects,advantages and capabilities inherent in this invention will becomereadily apparent from the description thereof which follows.

A further object of the invention is the provision'of a simple andaccurate gunsight assembly or mechanism which can be made extremelyeconomically and certain of the parts of which may be made from metalstampings and closely fitted together so as to maintain accuracy, thestructure being constructed and arranged to provide for both verticaland lateral or horizontal adjustment of the sight piece to compensatefor range distance variations and Wind deflections.

This invention further resides in the combination, construction andarrangement of parts illustrated in the accompanying drawings, and whilethere is `shown therein preferred embodiments of the invention, it is tobe understood that the same are susceptible of modification and changewithout departing from the spirit of the invention. Y

The accompanying drawings illustrate a selected embodiment of theinvention, and the views therein are as follows:

Fig. `1 is a fragmentary side elevation of a gun embodying theinvention;

Fig. 2 is an end view of a device embodying the invention, looking tothe left in Fig. 1;

Fig. 3 is a sectional view along the line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken along the line 4-4 of Fig. 2;

Fig. 5 is a fragmentary side view of a gun embodying a modified form ofthe invention.

The particular device herein disclosed for illustrating the inventioncomprises a supporting frame |0 having a bracket portion and anangulated portion I2 arranged in' angular spaced relation with thebracket portion. As shown in Fig. 2 the bracket portion is provided withspaced opening I3 for receiving screws I4 which are threadedly receivedin correspondingly spaced openings provided in the receiver I5 of a gunI6.

The angulated portion I2 of the supporting frame extends from one end ofthe bracket portion transversely of the gun from one side thereof to theopposite side approximately, as shown in Fig. 2, with the under surfaceof the portion I2 in abutting relation with the adjacent portion of theupper surface of the gun. The

portion I2 includes an angular upstanding portion or plate Il having agenerally rectangular, elongated, central opening |8 and spaced slitsI9, which define the outstruck portions forming lugs or straps 20connected by integral intact parts. The slits I9 and the outstruckportions 20 are arranged to receive a plate or bar 2| in substantiallyparallel, and freely slidable relation longitudinally of the frameportion or plate Il. The slits |9 are arranged to enable slight movementof the bar 2| lengthwise of the slits as well as freely slidablemovement of it in a direction at right angles thereto.

The bar 2| has a generally central cut-away portion 22 for receiving thesight piece or peepsight supporting bar 23 in freely slidable relationtransversely of the bar 2|. The cut-away portion 22 and the outstruckportions 20 are arranged to enable movement of the bar 23 and the sightpiece or peepsight 25 supported thereon in a -direction generally atright angles to the direction of freely Slidable movement of the bar 2|and intermediate adjacent surfaces of the bar l2| and the upstandingportion of the frame, as shown in Fig. 3.

The bar 23 has part threads on its opposite edges 24 and carries anadjusting nut 26, which is turnably received in that portion of theopening I9 intermediate the upper edge 2l of the bar 2| and the adjacentedge 28 of the frame.

The bar 23 and the nut 26'are arranged so that one face of the nut willbear on the adjacent edge 2l of the bar '2|. The opposite faces of thenut 26 are normally maintained in tight frictional engagement with theadjacent edges 2l and 28 by the action of a spring member 29 which ismounted adjacent one end thereof on the frame portion I2, as by means ofa vscrew 30 and extends therefrom rearwardly of the gun through anopening 3| provided in the frame.

The spring member 29 has an angulated, generally V-shaped portion 32arranged to receive the lower edge 33 of the bar 2|, as shown in Fig. 3,and acts normally to urge the bar up- Wardly to cause the upper face ofthe adjusting nut 26 to bear against the edge 28 of the frame and tomaintain the opposite faces of the nut in tight frictional engagementwith the adjacent edges 21 and 28. The opening I8, the slits I9, theoutstruck portions 20, the nut 26, the bar 2|, and the spring member 29are conformed and arranged so that the spring member will act normallyto c-ause frictional engagement between adjacent surfaces of the bar 2|and the frame portion l1, thus restricting movement of the bar in adirection longitudinally thereof simultaneously with the restriction ofmovement of the nut 26 in the manner stated. If desired, the edge 28 maybe a knife edge and the opposite faces of the nut 26 may be corrugatedor otherwise roughened as by providing radial corrugatilons therein forcooperation with the adjacent edges 21 and 28 and the lower edge of thebar 2| may have corrugations therein for cooperation with the portion32, as by extending the scale marks 35, which are provided on the facethereof to cooperate with the index point 36 provided on the springmember 29.

A knurled end portion 34 is provided on the spring member 29 remote fromthe screw 30 to facilitate manipulation of the spring member downwardlyfor the purpose of simultaneously releasing the bar 2| and the nut 26from the action of the spring. A finger piece, groove or roughenedsurface 31 may be provided on the bar 2i to facilitate adjustmentthereof when the spring member 29 is thus released.

The frame I1, the bar 2|, the bar 23, and the spring member 29 may -beof heat treated steel or other suitable material.

The described arrangement provides an economical and efficient devicefor use on a gun requiring ready, accurate adjustment of a peepsight intwo directions at right angles to each other.

In a modified form of the invention shown in Fig. the supporting frameis shown as mounted on the tang 38, for which purpose the bracketportion ll is dispensed with and the angular portion 39 is secureddirectly to the tang as by means of the screws 40.
